HEATER non PERMANENT HAIR wAvING,

Application filed March 22, 1924, Serial No."701,154. Renewed, December 5, 1925.

nentha1r Waving appliances, andrefers more particularly to those ,such appliances which are employed for applying heat to a strand ,of hair coiled upon a curler, so as to impart permanency to the wave. Such appliancescommonly comprise a tubular chamber adapted to receive a curler with the hair wound thereon and onev or more heating devices, generally electrical, associated with 2 the outsideof. the tube.

The present lnvention has for its object to improve the action of such heating appliances, firstly by causing the heat to be applied more particularly to the portion of the comprises ceive a coiled strand of hair, a cylindrical.

air nearest the root and secondly by enabling the heat to be applied either to the root portion only or more or less uniformly I to the whole of the hair under treatment. The appliance according to the invention metallic tubular member to reheating device around and spaced'from one end portion of the tubular member, and. a metallic i'ing or. sleeve disposed and establishing heat conductive communication between the end portions only :of the heating device and tubular member. In the construction hereinafter described by way of example, an adjustable device is provided for establishing heat conductive communication at will between the other end portion of the heating-device and the portion of the tubular memberprojecting through the heating device; Preferably such adjustable device consists of aitube or sleeve slidable on the tubular member so that one end thereof" can enteror withdrawfrom the space between the heating device and the tubular member at'will.

'In order that my invention may be clearly 'understood and more readily carried into practice, I have appended hereto one sheet of drawings illustrating-the same, where- Eights tie a 0 fpective as of as construction of appliance according to the invention, v rFigure 2 is .a sectional elevation of the appliance, J Figures 3', 4, 5 and 6 are views of disassembledparts, and

Figure 7 is an end view of the parts shown in. Figures 4 and 6 assembled.

The tubular heating chamber 1, which is made of aluminium or other suitable metal,

may be open, but as shown is closed at one end by a plug 2 having a hole to permit the escape-of moisture, and is flanged at the other end, a recess 3 being pressed up in the periphery of the end of thef tube'to permit the assage of the hair into the tube 1. Upon t eopen end of the tube 1 is arranged an electrical heating device consisting of an outer cover 10 and a ring 9 of heat insulatin material, an inner metal tube 5 covered wit a layer of insulating material such asgmica, and a winding of resist ance wire 8 covered by a layer'of asbestos '7. The tube5 is fitted in the ring 9 and chamber 1. l

.85 being normally transferred in any other manner-fronrthe tube 5 to the Slidable upon the portion of the tube 1 projecting from the heating device is a metal tube 12 'fitting snugly on the tube 1 and fitted into a sleeve-'13 of heat insu-' lating' materiaL, The tube 12 maybe split longitudinally as shown at 14;(F 1gure 3) and is slotted near its free end at 15. Screws 16 pass through the cover 10, ring movement'of the tube 12, but also to clamp e heating device into position. v

If it is desired,} as infre-wavmg only to heat 12 is pulled to tl'1eleft (Fig1 ire so as to be clear of the tube 5, but if t is desired, as in waving straight ban, to heat the hair,

hair, more orlless uniformly throughout its length, the tube 12 is moved to the bright, when it engagesin the end of the tube 5 and then forms another 7 pass from; the tube 5 to thetube 1." The when of he t be time t the mg .9, and slots 15, and serve not only to limit,

the hair near the roots the tube path for the heat to y heating device an 11, but. the heat conducted thereby is distributed over a longer length of the chamber 1 so that the greatest heat is still obtained where required near the roots of the hair.

The open 'end of'thechamber 1 may be fitted with any kind of closure adapted to allow passage of the hair into the chamber 1, but preferably a movable rubber faced cover 17 pivoted between links 18 and operated by a bridge piece 19.

Preferably a small piece 20 of sheet cork or other heat insulating material is inserted into the end portion of the cover 10, behind the recessed portion 3 of the tube 1, so as to prevent that portion of the tube 1 from collecting heat from the end of the heater tube 5 and thereby becoming hot enough to burn the hand should it come into contact with the recessed portion 3 or any other part of the edge of the tube 1.

What I claim is 1. An appliance of the kind set forth, comprising a metallic tubular hair receiving chamber, a tubular heating device surround-' ing and spaced from said chamber throughout its length, a metallic sleeve interposed between said heating device and said chamber so as to provide one path for the transfer of heat from the former to the latter, and adjustable means comprising a metallic member adapted to be moved to control a second path for the transfer of heat from the heating device to said chamber.

2. An appliance of the kind set forth, comprising a metallic tubular hair receiving chamber, a heating device surrounding and spaced from one end portion of said chamber, a metallic ririg disposed betweenthe end portions only of the heating device and tubular mem er, and an adjustable member adapted to be interposed between and to contact with the o posite end portion of the d the portion of the tubular chamber projecting therethrou h, so as to permit. the conduction of heat rom the {,ieater to an intermediate .part of the chamer. s

3. An appliance of the set forth,

' comprising a metallic tubularhai-r receivin chamber, a heating device surroundin an spaced from one. end portion. of said c amher, a metallic ring di between the end portions only of the heating'devic'e and tubular member, and a metallic sleeve slidable externally, along said chamber into andout of a pos tion in which one end thereof ongages, and provides heat conductive connection between the medial portion of the chamber and an end portion of the heating device.

4. An appliance of the kind set vforth, comprising a metallic tubular hair receiving chamber, a heating device surrounding and comprising a metallic tubular hair receiving chamber, a heating device surrounding and' spaced from one end portion of said chamber, a metallic ring disposed between the end portions only of the heating device and tubular member, a metallic sleeve slidable externally along said chamber into and out gages, and provides heat conductive connection between the medial portion of the chamber and an end portion of the heating device, a pin and slot connection between the sleeve and the heating device to limit sliding movement of the sleeve on the tu bular member, and a sleeve of heat insulating material secured to said metallic sleeve.

6. An appliance of the kind set forth, comprising a metallic tubular hair receiving chamber, a heating device therefor, and means, including fixed means and adjustable mechanical .means, adapted to apply the heat of said device to one end portion of said chamber in one position of adjustment of the adjustable means, and to both end portions of said chamber in another position of adjustment of said adjustable means.

7. An' appliance of the kind set forth, comprising a metallic'tubular hair receiving chamber, a heating device therefor, and me- \ARNOLD 'gisNRY BONGERS.
